Abstract

The invention provides an SIM card processing method and device, a terminal and an ESAM chip. The SIM card processing method comprises steps of obtaining a card number of an SIM card which is inserted into a terminal, adopting an embedded type safety module ESAM chip which is used for performing authentication on the card number of the SIM card, and performing authentication on the obtained card number of the SIM card. The SIM card processing method and device, the terminal and the ESAM chip solve a problem that in the prior art, authentication is performed on the SIM card through a software algorithm, which cannot guarantee safety and reliability of the authentication, and improves safety and reliability of the SIM card authentication.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a Subscriber Identity Module (Subscriber Identity Module, referred to as SIM) card processing method, device, terminal and embedded security module (Embedded Secure Access Module, referred to as ESAM) chip. Background technique [0002] In related technologies, since terminals (for example, mobile phones) are often lost or stolen, many terminals are provided with a function of authenticating an inserted SIM card. However, when authenticating the SIM card accessed by the terminal, a software algorithm is generally used for authentication. Even if these functions are set, they can generally be cracked through software codes. Once cracked, lost or stolen terminals can still be used. [0003] Therefore, in the related art, there is a problem that the security and reliability of the authentication cannot be guaranteed because the SIM card is authenticated by means of software algo...
